劳大家帮我看看，为什么总是报if(form1.2_ytbyx.value==""){错误，说缺少‘（’？万分感谢！
<input type="button" name="Submit" value="提交" onClick="process() "></td> <script> function process(){ //alert("开始检验!"); if(form1.2_ytbyx.value==""){ alert("您所输入的分值不能为空!"); form1.2_ytbyx.select(); }else if(checkscore20(form1.2_ytbyx.value)!=true){ alert("您输入的分值不正确！当前分值不应超过20分!"); form1.2_ytbyx.select(); return(false); }else{ var ytbyx = parseInt(document.getElementById("2_ytbyx").value); //alert("您输入的数值通过检验！请确认!"); } 回复讨论(解决方案)
完全是js的代码，没看到php的
因为报错只有这一段所以摘录了一下，主要程序如下：

改下input的name命名试试，不要数字开头
听楼上的建议。所有的input改为名字_数字的形式。
如1_mnbr => mbnr_1
否则会报js warning 的。
不明白的是，你的怎么会报php错误。
不是听楼上的建议，而是遵从变量命名规则
不守规矩，当然是后果自负
变量命名规则：以字母或下划线开头，后跟若干个字母、数字、下划线
的确是命名规则出了问题，看来还是踏实系统地学习啊！谢谢各位了！
